From Monday, November 3 to Sunday, November 9, 2025, significant disruptions will affect the metro, RER, and Transilien lines in Paris and the Île-de-France region due to ongoing modernization work.
After a relatively calm period, the RATP and SNCF networks are resuming essential upgrade projects. These works will lead to service interruptions and replacement buses on many routes throughout the region.
To minimize travel disruptions, passengers should check the official RATP and SNCF Connect apps before each trip. The Île-de-France Mobilités website also provides real-time travel alternatives.
